Interface And Graphics/whats The Difference Between Drawline And Draw Path

Oct 13, 2008

Is there any way to have 2d graphics that gets made by user through manual dimensions input be bound to a text box?

Also, whats the difference between drawline and draw path? How can I get the shape to remain on screen when I toggle between pages?

Difference Between 2 Arrays Declaration?

Jul 21, 2011

The Param1 works but param2 failed when passing it to method with object array parameter

Dim param1() As Object = {5, 5}
'And
TextBox2.Text = "5,5"
Dim param2() As Object = TextBox2.Text.Split(","c)
RichTextBox2.Text = CType(InvokeDllMethod(bt, "kayTestDynamicAssembly.KayTestDLL", "Addup",
param1), String)

My main question is that does .NET treat those 2 declarations differently or maybe I am missing something?

New Object Declaration Syntax?

Oct 30, 2010

I am using Visual Basic Express 2008 to make a simple game. I am trying to declare a dataset object and datatable but I'm getting a bizarre syntax error and I can't find a help reference.

Line A - I dimension GameTable  as an Object
Line B - I instantiate the object
Line C - I edit data in the GameTable
Line D - I display the data in Visual Basic 

Line C will crash in runtime if I don't do sometype of "New" declaration

Line B is my attempt at a "New" Declaration by I get an error message I don't understand - "Type Expected" - I think I have the syntax wrong here.

.net - Difference Between Declaring And Constructing A Value Type Object?

Oct 2, 2009

I've been working in .NET for some time now, but occasionally I still get confused by a disparity between the framework and my prior experience in C++.In .NET, all objects are either value types or reference types. Reference types are allocated on the heap while value types are allocated on the stack (in the current CLR implementation, anyway). I get that. However, at least in VB.NET, you can still define a constructor on a value type.

Public Structure Coordinates
Public x As Integer
Public y As Integer

Initializing Object Variables - Difference Between Methods

Jan 20, 2009

In VB.Net is there any difference between the following three ways of initializing object variables

Method 1
Dim commandObject As SqlCommand
commandObject = New SqlCommand("MadeUpCommand")

Method 2
Dim commandObject As SqlCommand = New SqlCommand("MadeUpCommand")

Method 3
Dim commandObject As New SqlCommand("MadeUpCommand")

Is one more efficient than the others, or are they effectively all the same?

C# - Whats The Point Of Tuple (Of T)

Sep 30, 2011

Possible Duplicate: What's the purpose of the Tuple(T1)/Singleton in .net?

Trying to mimic a Tuple as implemented in .Net 4 (For .Net 3) I just realized there is a Tuple(Of T)? This was quite a surprize!

Tuple<string> result = new Tuple<string>("Data");

Instead of this

return "Data";

Isn't the whole point of a tuple that its a container for "loosely related data that isnt cohesive enough to make another class"?

VS 2008 Whats The Better For Next Loop?

Mar 25, 2010

I have a question, i have worked in several languages in my life (including several versions of basic) but i wonder whether in .NET using a variable or equation in a loop is a lot slower than not using one? Take the following identical loops

Dim test(999) As Integer
For count As Integer = 0 to 999
test(count) = count
Next

[Code]...

Now the 2nd case is good because it is easier to adjust the code should the array size need to change yet my background tells me the 1st case is the one in terms of performance, test.Length - 1 is calculated each time the loop runs. a loop of the 2nd kind for example has a massive effect on java as well as VBscript or javascript.So heres the question, would test.Length - 1 be calculated each time the loop ran, or just the first time?
